About this file
This is a technical specifications document for Section 230523 - General-Duty Valves for HVAC Piping, part of Project 25-388 CBI HVAC and Lighting Upgrade. The specification details requirements for multiple valve types including angle valves, globe valves, ball valves, butterfly valves, check valves, gate valves, and plug valves for use in heating, cooling, and steam piping systems. The document establishes comprehensive technical standards referencing industry codes and standards such as ASME B16 series standards, MSS SP standards, and ASTM specifications. Valves are categorized by application including chilled water, condenser water, heating hot water, low pressure steam (15 psi or less), high pressure steam (greater than 15 psi), and steam-condensate systems. Specifications vary by pipe size, with different materials and pressure ratings required for applications ranging from 2 inches and smaller (primarily brass and bronze valves with threaded ends) to larger sizes requiring iron valves with grooved or flanged ends and varying pressure ratings from 125 to 300 CWP.
The specification requires valve manufacturers to demonstrate at least three years of documented experience specializing in valve manufacturing and mandates obtaining each valve type from a single manufacturer. Valve end connections must comply with established standards, with threaded ends specified for smaller pipes and grooved or flanged ends for larger applications. Installation requirements include providing unions or flanges to facilitate equipment removal, supporting valves with stems at or above pipe centerline, and installing chainwheels on operators for valves four inches and larger located 96 inches or more above finished floor. Submittals must include manufacturer product data, performance ratings, weights, support requirements, operation and maintenance documentation, and warranty information registered in the owner's name. The specification requires one wrench for every five plug valves in each size of square plug valve head to be furnished to the owner as maintenance materials.
